Given numbers are 249,417,973,120,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,417,973,120,172 is 416716440.
Find LCM of 249,417,973,120,172 with Prime Factorization
| 2 | 249, 417, 973, 120, 172 |
| 2 | 249, 417, 973, 60, 86 |
| 3 | 249, 417, 973, 30, 43 |
| 139 | 83, 139, 973, 10, 43 |
| 83, 1, 7, 10, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 139 x 83 x 1 x 7 x 10 x 43 = 416716440
Therefore, the lowest common multiple of 249,417,973,120,172 is 416716440.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
249 x 417 x 973 x 120 x 172 = 2085249065760
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
249 : 1, 3, 83, 249
417 : 1, 3, 139, 417
973 : 1, 7, 139, 973
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,417,973,120,172, is 1.
Now, the common factors can be found like this.
249:3x 83
417:3x 139
973:7x 139
120:2x 2x 2x 3x 5
172:2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 139 = 5004
Therefore, the value for common factors is 5004.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 2085249065760/(1x5004)
LCM = 2085249065760/5004
LCM = 416716440
Thus, we can understand that the LCM of 249,417,973,120,172 is 416716440.
